text: The chemical kinetics of a radical reaction depend on all these individual reactions. In steady state the concentrations of initiating (I) and terminating species T are negligent and rate of initiation and rate of termination are equal. The overall reaction rate can be written as:
  with a broken-order dependence of 1.5 with respect to the initiating species.
  The reactivity of different compounds toward a certain radical is measured in so-called competition experiments. Compounds bearing carbon–hydrogen bonds react with radicals in the order primary < secondary < tertiary < benzyl < allyl reflecting the order in C–H bond dissociation energy
  Many stabilizing effects can be explained as resonance effects, an effect specific to radicals is the captodative effect.
